Abstract: The present invention relates to anti-microbial compositions that may advantageously be added to vase water of cut flowers in order to prevent microbial growth, especially in vase water containing added cut flower nutrients and/or water uptake stimulants. One aspect of the invention relates to the use of an EC 1.1.3 oxidoreductase as an antimicrobial additive for vase water of cut flowers. Another aspect of the invention concerns a method of putting cut flowers into vase water, said method comprising immersing the stems of one or more cut flowers into vase water and adding an antimicrobial composition containing an EC 1.1.

Abstract: The present invention provides a method of preserving cut roses in the absence of a water supply. The method comprises: (a) cutting roses having a flower bud or a bloomed flower; and (b) packaging the cut roses in a container without immersing or inserting the stems in a hydration system. Instead, the cut roses are treated before or during the packaging by applying a preservation composition onto the flower buds or bloomed flowers The preservation composition contains at least 5 ppm of plant hormone selected from cytokinin, gibberellins and combinations thereof. A flower shipment kit is also disclosed.

Abstract: A sachet assembly, includes a closed bag which is formed from water-permeable filter paper, and a solid substance which is contained in the bag and is at least partially water-soluble. The water-soluble solid substance comprises a preparation for cut flowers. In particular, the preparation comprises a foodstuff and/or conditioning agent and/or disinfectant and/or biocide and/or growth inhibitor. The packaging assembly includes a waterproof, or at least moisture-proof, outer packaging containing a large number of sachets. The invention also relates to the use of a sachet made from water-permeable filter paper for administering a preparation to cut flowers which are standing in water.
